Python Programming

Question 1

            Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,
between 2000 and 3200 (both included).
            The numbers obtained should be printed in a comma-separated sequence on a single line.

Solution:

l=[]
for i in range(2000, 3201):
    if (i%7==0) and (i%5!=0):
        l.append(str(i))
print (','.join(l))

Question 2

Write a program which can compute the factorial of a given numbers.

Solution:

def fact(x):
  if x==1:
    return 1
  return x*fact(x-1)

y=int(input())
print(fact(y))

Question 3

Write a program to generate a dictionary that contains (i, i*)

Solution:

p={}
n=int(input())
for i in range (1,n+1):
  p[str(i)]=str(i*i)
print(" ".join(p))
pp=p.values()
print(" ".join(pp))

Output

10
1 2 3 4 5 6 7 8 9 10
1 4 9 16 25 36 49 64 81 100

Question 4

Write a program to check if two strings are anagram

Solution:

def anagram(s1,s2):
  return sorted(s1)==sorted(s2)
  
a="ababa" #string 1
b="ababa" #string 2

print(anagram(a,b))

Question 5

Write a program to check if given strings are palindrome

Solution:

a="malayalam"

def check_palindrome(s1,s2):
  return s1==s2

print(check_palindrome(a,a[::-1]))

Question 6

Find the Missing Number

Solution:

a = [1,2,3,5]


#as we know (n)*(n+1)/2 gives sum of n numbers

# "sum_if_series_were_completed" corresponds to sum of [1,2,3,4,5]
# "sum_of_missing_series" corresponds to sum of [1,2,3,5]


def find_miss_no(series):
  p = len(series)
  sum_if_series_were_completed = ((p+1)*(p+2))/2
  sum_of_missing_series = sum(series)
  return sum_if_series_were_completed-sum_of_missing_series

print(find_miss_no(a))

Question 7

How do you debug a Python program?

Solution:

python -m pdb prg_name.py
pdb -> python debugger

Question 8

Print space seperated integers on a line denoting first N squares in the ascending order

Solution:

p=int(input())

for i in range(p):
    pp=i+1
    cc=pp*pp
    print( cc, end=" ")

Output

  10
  1 4 9 16 25 36 49 64 81 100

Question 9

Convert Celsius To Fahrenheit

Solution:

celsius = 37.5

# calculate fahrenheit
fahren = (celsius * 1.8) + 32
print('%0.1f degree Celsius is equal to %0.1f degree Fahrenheit' %(celsius,fahren))

Output

  37.5 degree Celsius is equal to 99.5 degree Fahrenheit
